Here the code:

        return _query

    def _plugin_request( self , _file ):
       pass

    def _requests( self , _plugin ):
       pass

    def _run( self , _user_email , _domain , _batch_size = 25 ):
        if _domain:
            self._user_email = _user_email
            self._domain = _domain
            memcache.add( hashlib.sha512( 'analysis: ' + _domain 
).hexdigest() , True )
            self._continue( None , _batch_size )

    def _continue( self , _start_key , _batch_size ):
        _query = self._query()
        if _start_key:
            _query.filter( "__key__ >" , _start_key )
        try:
            for _counter , _plugin in enumerate( _query.fetch( limit =

                self._requests( _plugin )
                if not _counter % _batch_size:

            if not _query.fetch( limit = _batch_size ):
                self._finish()
        except DeadlineExceededError:
            deferred.defer( self._continue , _start_key , _batch_size)
